Forms :: VScrollbar Scrolls With Left/Right Arrows?
Jan 14, 2010
I have a fairly simple VScrollbar problem: the Scroll event triggers when ANY arrow key is pushed, including left and right... I need it to trigger only when up/down arrow keys are pushed (which, I hope, is the default behaviour).
Essentially all I do is declare a VScroll As System.Windows.Form.VScrollBar and later I have a Private Sub VScrollBar_Scroll (...) Handles VScroll.Scroll that manages the event.
I noticed also that the left/right arrow scrolling is by a smaller increment than the up/down scrolling. All of this seems to happen in a very "black box" kind of way, I can't find any way of determining what should trigger the scroll event.

Im building a, lets say kiosk, that has only one form of input and that is a keyboard. I've got an up/down/left/right arrows and the enter button. I have a form that needs to have hundreds of buttons. I've arranged all my buttons in a giant grid and want the user to use the arrows to navigate through the buttons. The button that is 'highlighted', lack of a better term, has different colors so we know which button we currently are on. So when the user hits the down arrow the button below the current button gets highlighted. My issue is that when the user hits the left and right arrows the 'cursor' doesnt move left and right it moves up and down.
The left and right arrows follow the tabindex sequence.

I am trying to use values from form1 in my project, in form2, but Im not sure how to do it. I've tried
txtboxTotal = (Form1.vsbLength * Form1.vsbWidth) * Pattern
But I get: operator '*' is not defined for types 'System.Windows.Forms.VscrollBar' and 'Systems.Windows.Forms.VscrollBar.'

My code is basically a file parser/editor and it handles most files fine as they hold a handful of records concerning family members. However there are a few files that crash when trying to deal with them. Here is the problem.Each family member record creates 3 tabs that hold an average of 3 group boxes each. Each group box holds an average of 3 text boxes.So each member record creates 3x3x3 = 27 text boxes and some files get up to 289 family members which = 7803 text boxes.
The problem is the rare file with 400+ member records = 10,800 text boxes which causes a crash due to using up all the window handles. Each member has a separate tab page (with 3 subpages) but really only a dozen or so member pages are visible in the GUI with scroll arrows to move through them so I was thinking of somehow making the GUI a scrollable window so the tabs get built, displayed and disposed as the user scrolls left and right through the member tabs.
The files are parsed into a 3d list DataList(x,y,z) where x is the page number, y is the group box number and z is the text box number. So all the data is available. The code then traverses MyList and builds GuiList(x,y) where x is the page number and y is the groupbox number with all the textbox.text linked to MyList(x,y,z) locations so all text changes are reflected in the MyList.
I already have a memberCount variable and I am thinking of building, say, the first 30 member tabs with the middle 10 being visible in the GUI. If the selected tab > 20, then dispose of the first 10 tabs and create tabs 30-40.I am thinking I will keep all the member tab pages so I don't have to deal with inserts and indexing problems but just dispose all the group boxes and text boxes for tab pages out of view. I already have a deep clone sub that clones members when the user wants to add a new family member and I am thinking I will have to add something similar when a tabpage is passed in for disposal, it traverses and disposes each text box, then disposes the group box for each group box on the tab page.Additionally, another routine will rebuild the group boxes from the data held in MyList(x,y,z) when a tabpage(x) is passed in.

I am using VB .NET. I want to know how to make the scroll-up and down arrows visible for my text boxes if the user wishes to enter more lines of text than the size of the text box can take. I would like the user to be able to scroll up and down after he/she has entered all the text.
How do I activate this property - should I be using some other control other than a text box for this?

I have code to create a listbox and populate it, and would like the box to behave like it does when clicked, e.g. if you CLICK on "a" you see it blue and can press the down arrow to move down to "b". how do I achieve this programmatically?
Private Sub junkloader()
brandlist.Visible = True
brandlist.Items.Clear()
brandlist.Items.Add("a")[code].....
this code SELECTS it properly, but I want to be able to navigate with the up and down arrows. how do I do this? thanks.

I would like to display 2 forms side by side. Frm1 will call Frm2. The problem is, if Frm1 is too near the edge of the computer screen, when Fr2 is shown, part of it will be outside the screen. How do I make it so that if Frm1 is near the right-side of the screen then Frm2 will show on the left-side of Frm1 and vise-versa?

I'm using VS 2005 and .NET framework 2.0 SP2 to build an application with a datagridview in it. I'm using Microsoft Word 11.0 Object Library to do the spelling checker on one of the field in datagridview. When it detected a spelling and grammar window would pop-up open on top of the datagridview.
The problem I got was when I moved the pop-up window to the new location, there's still an image of the pop-up window left behind the previous location. The more I moved the more of those copied image would be created on screen.

Do the VScrollBar and HScrollBar controls have a known Value bug?I'm using VB10. While testing some code I used a Horizontal Scroll Bar to change a value on the fly, I thought my code had some bad math in it until I discovered that when the bar is scrolled to the very far right the Value was not equal to its Maximum value setting like it is in VB6, the same happens for the Vertical scroll bar control, set the maximum to 100 the Value will only go up to 91, set max to 200 and value only goes to 191, etc.

I was checking out the internet to get some information on VScrollBar control in VB.NET, however I can't find any useful information on what I am trying to do, as I have never worked with VScrollBar before.
What I am trying to do is use a VScrollBar control to handle scrolling of two Richtextboxes (i.e. synchronized scrolling) because each line of richtextbox1 is associated with the corresponding line of richtextbox2.

I'm looking to reverse the functionality of a VScrollBar in VB.NET - I would like the number to increase when the up button is pressed and decrease when the down button is pressed.I'm surprised that this issue isn't more commonly represented online, but I could find nothing online about making a VScrollBar work the way I want it to in VB.NET. Apparently in VB 6.0, you were able to flip the Min and Max values and this achieved what I desire to do, but they removed that feature in VB.NET

I have a windows form with a tool strip menu, a header and a datagrid view.
When I add auto scroll to the windows form the scroll bar scrolls through the whole windows form, I want it so that it only scrolls through the datagrid and the header and tool strip stay fixed and don't move.

I'm currently working on an application that detects a color on a defined area on the screen and together with a panel that displays the color I show the values in a label and represent them with a vscrollbar. (The goal of the project is to output the color of the computer screen via an usb to dmx interface to create an ambilight effect) Now I don't want the user to be able to move the scrollbars up and down so I figured disabling them would do the trick but then the little square you click on to scroll it up and down isn't visible anymore.

I have made an information display that is split in two parts. The right part shows a jpg converted document with picturebox and VB.Net. The picture changes if there is more documents to show. The left part is a webpage that is opened from the VB.Net program. It contains two xml newstickers in flash from [URL]. Both parts are feeded from a sql database. Everything works but I have a little problem with the newstickers. Everytime the right part with jpg converted document change document the newsticker scroll is jumping. Is there somebody who know a way to decrease the impact on the scrolls then I change document in the picturebox? Can I run the webpage in a other process or something? Or must I find another newsticker ?

I have a program that outputs a series of items onto a form--an "invoice" if you would like. The problem is, when the user enters in more items than the invoice's size can handle the rest just disappears into the mysterious realm down at the bottom. Is there a way where I can make the label automatically detect items going in and create a vscrollbar or something similar so that it can accommodate it's size?

I got a panel that i am adding labels to.

Is this even possible? Same thing with UP.
